Method for coiling a coiled product, control installation, computer software product, and coiling machine

Abstract

A coiled product, a control installation, computer software product, a coiling machine and method for coiling a coiled product, wherein the coiling tension is settable to an envisaged coiling tension, particularly to a constant coiling tension via either a setting unit and/or a change in the respective rotational speed of either a coil body and/or a supply roll, a characterizing aspect being the equalization of the free length of the coiled product, where the free length is the spacing of the first bearing point of the coiled product on the coil body from the second bearing point of the coiled product on a deflection roller such that the free length change is equalized by the setting unit and/or by a variation of the respective rotational speed so that coiling tension of a product coiled onto the coil body can be set in a simple, rapid, and precise manner.

What is claimed is: 
     
       1. A method for coiling a coiled product from a supply roll onto the coil body, the method comprising:
 providing the coiled product from the supply roll; and 
 winding the coiled product onto the coil body, a coiling tension of the coiled product being adjustable to an envisaged coiling tension provided by a control installation including at least one of a computer unit and a regulation unit; 
 wherein at least one of (i) a rotational speed of the coil body is controlled or regulated to set the coiling tension and (ii) the coiling tension is set to the envisaged coiling tension by a setting unit. 
 
     
     
       2. The method as claimed in  claim 1 , wherein the envisaged coiling tension is constant. 
     
     
       3. The method as claimed in  claim 2 , wherein the setting unit has a variable coiled-product accumulator. 
     
     
       4. The method as claimed in one of  claim 2 , wherein the setting unit, between a third bearing point of the coiled product on the supply roll and a first bearing point of the coiled product on the coil body, sets a length of the coiled product to a constant length. 
     
     
       5. The method as claimed at least in  claim 4 , wherein the setting unit equalizes a change in a free length. 
     
     
       6. The method as claimed at least in  claim 4 , wherein the setting unit equalizes the change in the free length in conjunction with the coiled-product accumulator. 
     
     
       7. The method as claimed in  claim 1 , wherein the setting unit has a variable coiled-product accumulator. 
     
     
       8. The method as claimed in  claim 1 , wherein the setting unit has an adjustable coiled-product brake. 
     
     
       9. The method as claimed in  claim 1 , wherein the coiling tension is set to the envisaged coiling tension by a regulator installation. 
     
     
       10. The method as claimed in  claim 1 , wherein one of (i) an encoder and (ii) a force transducer determines the coiling tension. 
     
     
       11. The method as claimed in  claim 10 , wherein the encoder comprises an encoder on a dancer roller. 
     
     
       12. The method as claimed in  claim 1 , wherein at least one parameter for the setting unit is calculated when coiling. 
     
     
       13. The method as claimed in  claim 1 , wherein the at least one parameter comprises a position of an actuator. 
     
     
       14. The method as claimed at least in  claim 1 , wherein the setting of the coiling tension is performed via rotational speed of the coil body. 
     
     
       15. The method as claimed in  claim 1 , wherein the coiled product comprises wire or a film and the coil body has a non-circular cross section. 
     
     
       16. A non-transitory computer-readable medium encoded with a computer program executed by a computer unit that causes a coiling machine to begin coiling a coiled product from a supply roll onto a coil body, the computer program comprising:
 program code for providing the coiled product from the supply roll; and 
 program code for winding the coiled product onto the coil body, a coiling tension of the coiled product being adjustable to an envisaged coiling tension provided by a control installation including at least one of a computer unit and a regulation unit; 
 wherein at least one of (i) a rotational speed of the coil body is controlled or regulated to set the coiling tension and (ii) the coiling tension is set to an envisaged coiling tension by a setting unit. 
 
     
     
       17. A control installation for a coiling machine, the control installation comprising:
 a control unit including at least one of a computer unit and a regulation unit; 
 a setting unit; and 
 a plurality of drives; 
 wherein the control unit aided by at least one of (i) the plurality of drives and (ii) the setting unit is configured to: 
 provide a coiled product from a supply roll; and 
 wind the coiled product onto the coil body, a coiling tension of the coiled product being adjustable to an envisaged coiling tension; 
 wherein at least one of (i) a rotational speed of the coil body is controlled or regulated to set the coiling tension and (ii) the coiling tension is set to the envisaged coiling tension by the setting unit. 
 
     
     
       18. A coiling machine including the control installation as claimed in the  claim 17 . 
     
     
       19. The coiling machine as claimed in  claim 17 , wherein the coiling machine coils wire or a film.
